Abstract
Main topic:
Paradise Lost- A Fragile Environmental Recovery
Assess a degraded ecosystem by gathering historical and current evidence.
Sub-topics:
* Understand an estuary in terms of its abiotic and biotic components
* Investigate how pollution degrades an ecosystem
* Understand how humansinfluence ecosystems
* Research ecological best management practices
* Implement ways to reduce, reuse, recycle and restore
* Create a proposal to restore or preserve an ecosystem
Methodology:
In the Jason Project I used as sources of information:
* Google Earth
* Resilient Planet Book
* Internet (Google)
* Science notes
* Jason mission center webpage
Summary: Inthe last past years, many people all over the world have settled around estuaries. Almost half of the world’s fisheries depend on estuaries. The source of water, fertile soil, fishing, and the large biodiversity of the estuary ecosystem makes it a popular human habitat.
The total number, diversity, and complexity of abiotic and biotic factors make understanding natural systems, as estuaries,extremely challenging.
Estuaries support a great variety of life, and it is because of its nutrient-rich waters carry a significant population of primary producers. Coastal forests, marshlands, shore grasses, and submerged aquatic vegetation (SAV) provide food and shelter for animals.
The productivity of estuaries has declined in recent years because many people have increased their settlementsalong their shores. Seven of the ten largest cities of the world have been settled on estuaries, they are Tokyo, New York, Shanghai, Calcutta, Buenos Aires, Rio de Janeiro, and Mumbai. Human settlements near rivers and in estuaries have been for years polluting in different ways the estuaries. Air composition has change; so many birds that usually use estuaries to rest from their migration are nomore stopping in them. The water composition in some estuaries has change, and oyster population in some estuaries has reduced. Soil in estuaries has been polluted because of much trash thrown to rivers and also directly to the estuaries. People must awareness about the importance of estuaries in the life of the planet. There are four simple things that people from the entire world can practiceto help preserve estuaries, as not only people who live near estuaries are the ones who contaminate them. These four things are reduce, restore, recycle and reuse.

Introduction
Have you ever thought of what will it be of our children if we don’t take care of our planet? How this world is going to be in the future? If we don’t take care of our environment future generations will not see what weare capable to appreciate. This world is full of natural environments; it includes the unique estuaries that exist all around the world.
An estuary is a short stream where freshwater meets with the ocean’s water and mix. This ecosystem is very important for the planet’s environment. They are also called “nurseries of the seas” because that’s where some animals go there, rest, and reproduce....
